Not a great angle on this shot, but it is the device on the very end of the primary throttle shaft, (on the right in this image below) with the 3-way triangle shaped connector coming off it.
Note that is the end opposite the throttle cables.
This image shows it better
This one, (below) on the opposite end is the secondary TPS
The 'thing' in his hand is the ISCV Stepper Motor
(Note that in these last 2 images, the throttle bodies are upside down)
I find EBay is a fabulous source for images of parts to see details!
